起初读

Every Android app has a unique application ID that looks like a Java package name, such as com.example.myapp. This ID uniquely identifies your app on the device and in Google Play Store. If you want to upload a new version of your app, the application ID (and the certificate you sign it with) must be the same as the original APK—if you change the application ID, Google Play Store treats the APK as a completely different app. So once you publish your app, you should never change the application ID.

如果您的应用程序不活包名后在游戏商店然后从这里改变

打开build.gradle

defaultConfig { 
    applicationId "com.companyname.xyz.xyz.asyncTasks" 
    ..... 
     } 

FYI

不要手动更改套餐名称。
